Polydacrys is a genus of broad-nosed weevils in the beetle family Curculionidae, subfamily Entiminae,[1] tribe Anypotactini, present across the Americas and the Caribbean. There are eight described species in Polydacrys.[2][3]
Taxonomy
Polydacrys was described for the first time by Carl Johan Schönherr in 1834 (p. 130).[4] It was previously considered a member of the Tanymecini.[5]
There is a key to the Central American species of Polydacrys in Champion (1911: 217).[6]
Description
Members of Polydacrys are small (~6 to 12 mm) and can be recognized by their nasal plate, which is triangular, large, glabrous, shiny, and elevated from the surface of the rostrum.[5] In addition, their mandibular scars are projected from the surface of the mandible.
Distribution
Members of Polydacrys range from Texas through Bolivia and are particularly well-represented across the Caribbean.[1]
